Abstract


This study examined the contents of bioactive compounds and the biological activity of okra seed oil. Okra seed oilconsisted mainly of linoleic acid (44.2%). The content of total phytosterols was 2.180 mg/g oil, with β-sitosterol being thehighest (1.756 mg/g oil). The vitamin E content was 1.278 mg/g oil; the content of α-tocopherol was higher than γ-tocopherol. The total polyphenol and flavonoid contents were 2.463 mg gallic acid equivalent/g and 1.602 mg cathechinequivalent/g, respectively. The 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid and α-α-diphenyl-β-picrylhydrazyl freeradical scavenging activities were 15.297% and 22.265%, respectively, and the reducing power was 4.524 mg gallic acidequivalent/g. The okra seed oil inhibited 77.692% of the α-glucosidase activity. The present study showed that okra seedoil had a considerable amount of phytochemicals and exhibited biological activity. These results suggest that okra seed oilis a potential natural therapeutic for the management of metabolic syndromes.
